This study assessed the concentrations of nine trace metals from juvenile C. falciformis caught from Indian Ocean. This study also discussed the metal pollution index (MPI) and bioconcentration factor (BCF) of each element, and their correlations. Further, the potential health risks of consuming shark muscles (THI) were evaluated. Results showed the mean concentrations of 9 elements as follows: Cu (0.36 ± 0.17), Zn (5.19 ± 16.6), Pb (0.12 ± 0.23), Cd (0.17 ± 0.21), Cr (0.57 ± 1.61), Ni (0.086 ± 0.51), As (1.36 ± 0.83), Co (0.000073 ± 0.0074), and V (0.0024 ± 0.0094) mg/kg ww. The BCF values of the elements were higher than 1, with Co and V being the lowest indicating their bioaccumulative behavior. Correlation analysis showed MPI to be highly correlated with Cu, indicating its greater contributions to the total pollution load. Principal components analysis explained 81.0% of the variability in biometric characteristics and metal concentrations. Health risk assessment for consuming shark muscle in Taiwanese male and female adults suggests potential chronic non-carcinogenic health hazards.
本研究评估了从印度洋捕获的镰状真鲨幼鱼体内九种痕量金属的浓度。本研究还讨论了各元素的金属污染指数（MPI）和生物富集因子（BCF）及其相关性。此外，还评估了食用鲨鱼肌肉的潜在健康风险（THI）。结果显示9种元素的平均浓度如下：铜（0.36±0.17）、锌（5.19±16.6）、铅（0.12±0.23）、镉（0.17±0.21）、铬（0.57±1.61）、镍（0.086±0.51）、砷（1.36±0.83）、钴（0.000073±0.0074）和钒（0.0024±0.0094）mg/kg湿重。各元素的BCF值均高于1，其中钴和钒最低，表明它们具有生物累积行为。相关性分析表明，MPI与铜高度相关，表明其对总污染负荷的贡献更大。主成分分析解释了生物特征和金属浓度变异的81.0%。对台湾成年男性和女性食用鲨鱼肌肉的健康风险评估表明存在潜在的慢性非致癌健康危害。
